Windfiend “Lord of All Fiends” is the leader of the Seamless Gate.
Windfiend was an ‘overlord’ character of the Seamless Gate, someone whose power and strength had reached the Elder God level. During the first war of the Primordial Era, Windfiend led the Seamless Gate's escape.
After the Endwar, Windfiend became the new leader of the Seamless Gate and led them in returning to the Three Realms. His other title was The Lord of all Fiends.
He was born an Elder Fiend of primordial chaos with full mastery of the Heavenly Dao of Wind of the Seamless Chaosworld.
Even as an Elder Fiend, he was able to escape with his fellows from the clutch of World God Nuwa.
